of my presidency. the most intense concentrated day that i've had as president of the united states. >> the president says everything was kept really close to the vest. the first lady didn't even know about it until after it happened. >> brian williams joining us on the phone right now. brian, we have to start by saying what an incredible look that was that you and your team provided inside what happened at the white house. there are a whole lot of things we'd like to ask you. what's the most amazing thing to you about the process of the whole bin laden raid and the strategy sessions that went into making that happen? >> well, doreen, jim, thank you. i think chiefly what we're proudest of is we were -- we asked for this opportunity. we were allowed in to kind of deconstruct and recreate that picture and talk to all the principles in it, the entire leadership of government. i think you happened upon it earlier. i think the secrecy, the close hold to use government parlance because if they'd missed that launch window for whatever reason that night, it might have been six more months.
